Protection up front, breathability in the back. The Nano-Air® Light Hybrid Jacket was created to put an end to the clam factor that often accompanies hefty aerobic effort in chilly temperatures and keep you at optimum operating temperature even on bad hair days. A light layer of warm, stretchy and breathable FullRange™ insulation (40-g) is wrapped in a lightweight yet durable, 100% nylon ripstop shell with DWR (durable water repellent) finish for just the right amount of wind- and weather protection up front. Everywhere else, a super stretchy, airy waffle knit swiftly wicks moisture, controls odor and dissipates heat. Other details include a sleek center-front zipper with a zipper garage that’s easy on the chin, stretch-knit cuffs with thumb holes to ensure critical coverage, low-profile zippered pockets for comfort under a harness or pack and a stretch binding hem to seal in warmth.

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.

Odor Resistant

Polygiene® odor control permanently protects your garments from smelling like a middle school locker room. Sweat itself is odorless, but it creates the conditions that bacteria need to multiply, and some of those bacteria produce odors. Polygiene permanent odor control stops the growth of odor-causing bacteria on fabrics, so you can wear more and wash less.

Active only on the fabric surface, Polygiene permanent odor control does not interfere with perspiration or with the skin’s natural bacterial flora. Polygiene particles are more than 100 times larger than nanoparticles and therefore are too large to penetrate to the skin’s barrier. Polygiene-treated fabrics have received Medical Class 1 approval in Europe, the same class that includes bandages.
